Firmware archive for a board numbered 6050A3147201, labelled MB-AX3, bundling both the system BIOS and the embedded controller firmware for a 32MB flash. The 6050A prefix follows the Inventec numbering pattern, so the board was designed by that ODM regardless of the laptop brand on the lid. Use it to reprogram the SPI chip with a programmer such as a CH341A or RT809H after a corrupted update. Read and save the original chip contents first, confirm the chip really is 32MB, and check the PCB print matches the number.</div>
